Answer : The concentration of the HCl in original bottle is 0.56 M.
Explanation :
According to neutralization law:
where,
= concentration of HCl
= concentration of NaOH
= volume of HCl
= volume of NaOH
Given:
= ?
= 0.25 M
= 10 mL
= 22.4 mL
Now put all the given values in the above formula, we get:
Therefore, the concentration of the HCl in original bottle is 0.56 M.
Answer:
0.0928 grams of oxygen was collected.
Explanation:
Volume of oxygen gas collected = V= 75.3 mL = 0.0753 L (1 mL = 0.001 L)
Temperature of the gas = T = 25°C = 25+ 273 k = 298 K
Pressure of the gas = P - = 742 Torr - 24 Torr = 718 Torr
1 atm = 760 Torr
Moles of oxygen gas = n
Using an ideal gas equation;
n = 0.0029 mol
Mass of 0.0029 moles of oxygen gas :
0.0029 mol × 32 g/mol = 0.0928 g
0.0928 grams of oxygen was collected.
Metals usually melt when forming iron
It is possible to turn aldehydes and ketones into alkenes via the Wittig reaction.
<h3><u>What is wittig reaction ?</u></h3>
- The Wittig Reaction: It is possible to turn aldehydes and ketones into alkenes via the Wittig reaction, which is a practical process.
- Georg Wittig, its creator, received the 1979 Nobel Prize in Chemistry for it (along with the father of hydroboration, H.C. Brown).
- A carbonyl molecule (aldehydes and ketones both function, but esters or amides do not) and a fairly peculiar-looking species known as a ylide are the two ingredients in this reaction. (more precisely, a "phosphonium ylide," as there are also ylides of nitrogen and sulfur).
- An ylide is a species having opposing formal charges on nearby atoms, according to technical definition. The ylide, which we shown above with a double bond between carbon and phosphorus, also has a significant resonance form with a positive charge on phosphorus and a negative charge on carbon.
